  Coronavirus - Wikipedia, the free encyclopedia
Coronavirus is a genus of animal virus belonging to the family Coronaviridae.
The name "coronavirus" draws reference to the "corona" -- the "ring-like radiating structure" formed by the outermost part of the atmosphere of the sun.
Feline enteric coronavirus is a pathogen of minor clinical significance, but spontaneous mutation of this virus can result in feline infectious peritonitis (FIP), a disease associated with high mortality.

 Coronavirus -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-21)
Coronavirus is a genus of animal ((virology) ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein) virus belonging to the family (Click link for more info and facts about Coronaviridae) Coronaviridae.
The naming of this fourth coronavirus is still a controversial issue, as the three labs are still battling over who actually discovered the virus first and hence earns the right to name the virus.
Early 2005, a research team at the University of Hong Kong reported finding a fifth human coronavirus in two (Respiratory disease characterized by inflammation of the lung parenchyma (excluding the bronchi) with congestion caused by viruses or bacteria or irritants) pneumonia patients, and subsequently named it HKU1.

 Coronavirus infection aka corona virus affects many dogs
Different members of the coronavirus family have a predilection for specific species; thus, a coronavirus infection in the dog is highly unlikely to be contagious to a person or other animal.
Because the coronavirus is highly contagious, animals that live in kennels or participate in dog shows are at a high risk for contracting it and should be vaccinated.
Canine coronavirus is passed on when a susceptible dog or puppy ingests feces from a dog that has the virus.

 CDC Media Relations - Telebriefing Transcript - March 24, 2003
Coronavirus is not a Paramyxovirus, it is not a Metapneumovirus.
This, in scientific terms, is very strong evidence supporting Coronavirus as an etiology, but we know from sequencing pieces of the virus DNA that it is not identical to the Coronaviruses that we've seen in the past.
Since the Coronavirus has not, as it seems, been known to be deadly before in humans, could you give us any information on what is different about this virus, maybe the origins of it, you know, anything you can tell us on that.

On rare occasions, gastrointestinal coronavirus infection has been associated with outbreaks of diarrhoea in children, but these enteric viruses are not well characterized and are not discussed in this chapter.
Coronavirus virions are spherical to pleomorphic enveloped particles (Fig.
Because coronavirus infections are common, many individuals have specific antibodies in their nasal secretions, and these antibodies can protect against infection.

 Coronaviruses
Coronavirus particles are irregularly-shaped, ~60-220nm in diameter, with an outer envelope bearing distinctive, 'club-shaped' peplomers (~20nm long x 10nm at wide distal end).
The number of coronavirus serotypes and the extent of antigenic variation is unknown.
Amplification of short regions of the polymerase gene, (the most strongly conserved part of the coronavirus genome) by reverse transcriptase polymerase chain reaction (RT-PCR) and nucleotide sequencing revealed that the SARS virus is a novel coronavirus which has not previously been present in human populations.

 CIDRAP >> New coronavirus may be SARS cause, CDC says
CDC experts have grown the coronavirus in cultures of tissue samples from SARS patients and have viewed the virus in electron microscope studies, Gerberding said.
Gerberding added, "This is not identical to the coronaviruses we've seen in the past, so this may be a new or emerging coronavirus infection." She explained that there are three groups of coronaviruses, but the genetic sequencing studies done so far indicate that this particular coronavirus does not fall precisely into any of them.
Further steps needed to confirm the coronavirus hypothesis include further culturing of the virus from appropriate specimens, sequencing of the viral genome, and examining specimens from patients at different stages of the illness, the CDC news release stated.

 Coronavirus Confirmed as Cause of SARS
But the virus identified as the cause of SARS appears to be a previously unknown member of the coronavirus family.
Although researchers had widely accepted this new coronavirus as the primary cause of SARS in recent weeks, a series of conditions known as Koch's postulates had to be met before it could be officially recognized as the cause.
Those conditions include: finding the virus in all cases of the disease, isolating the virus and culturing it in the lab from an infected tissue sample, reproducing the disease in a previously healthy host, and identifying the virus in the infected host.

The viruses collect in membrane bound sacs and are eventually released onto the surface of the cell in large numbers.
It then enters the cell by membrane fusion with the plasma membrane or by receptor mediated endocytosis (a clathrin coated vesicle is seen floating in the region).
The nucleus is shown in the lower right hand corner of the image and the N protein presumably enters through the nuclear pores (the flower-like structures decorating the surface of the nucleus).

 Exclusive - House Flies Can Spread Coronavirus
Avian Dis 2003 Jan-Mar;47(1):149-53 Mechanical transmission of turkey coronavirus by domestic houseflies (Musca domestica Linnaeaus).
So, Jeff, it is my reasonable guess that SARS coronavirus can be spread by house flies for between 3 and 72 hours after a fly has come into contact with SARS coronavirus as is likely to happen if a fly lands on any infected human waste/body fluids.
You will note that, for turkey coronavirus, it is sufficient to have one single infected fly land on a bird and the bird can become infected.

Now a paper entitled "Detection of human coronavirus NL63 from children with respiratory illness in 2003 - Sendai City" has appeared on the Japanese National Institute of Infectious Diseases web-site entitled "Detection of human coronavirus NL63 from children with respiratory illness in 2003 - Sendai City".

Coronaviruses are a common cause of mild to moderate upper-respiratory illness in humans and are associated with respiratory, gastrointestinal, liver, and neurologic disease in several animal species.
The new coronavirus was isolated from clinical specimens of two patients with SARS, cultured in Vero E6 cells, and then characterized by several laboratory methods.
Other serologic tests demonstrated that the new agent reacts with antisera to one of the three known coronavirus serogroups, but sequence analysis suggests that it is distinct from the known coronaviruses.
